Los Angeles -LRB- CNN -RRB- -- The lawsuit against Porsche related to the fiery crash that killed actor Paul Walker suffered a setback in court , but a lawyer says it will go on .

Roger Rodas ' widow is suing that carmaker 's North American branch , claiming negligence and a poor design of the high-powered Porsche Carrera GT caused the crash last November .

U.S. District Judge Philip Gutierrez dismissed four of the five grounds for the lawsuit , finding that the complaint did not include enough specifics . Rodas can revive the arguments by amending her lawsuit , Gutierrez said in an order filed in federal court Monday .

`` He only granted a partial dismissal with leave to amend , which we will , '' Rodas lawyer Mark Geragos told CNN Tuesday .

Kristine Rodas filed the suit against Porsche Cars North America in May , citing negligence as the cause of death of her husband and the 40-year-old `` Fast and the Furious '' star on November 30 in Santa Clarita , California . She also alleged product liability and wrongful death .

The only allegation that was not dismissed was the `` strict liability claim '' regarding the lack of a crash cage and racing fuel cell for the high-performance car .

The Rodas lawsuit contends that a `` properly functioning crash cage '' would have prevented the deaths by preventing `` intrusion into the passenger compartment , '' damage to the fuel tank , and the splitting of the vehicle in half .

Roger Rodas , 38 at the time of his death , spent his competitive racing career driving Porsche cars . According to the court documents , he and Walker first met on the race track when Rodas was driving a Porsche owned by the actor . A few years later the two men formed the racing team Always Evolving Racing , where they were both drivers .

`` Although Mr. Rodas had a passion for cars , Mr. Rodas was first and foremost dedicated to his family , his wife , Kristine , and their two young children , '' the complaint states .

The court documents filed by Kristine Rodas describe the 2005 Porsche Carrera GT that her husband was driving as a an `` ultra-high-performance-super-sports car for the road , '' that goes from zero to 60 mph in 3.5 seconds and has a top speed of 205 miles per hour . The complaint argues that such a high-powered sports car should have a higher standard of crash protection , and that a mechanical malfunction forced Rodas to veer off the road .

Geragos also hired investigators to evaluate wreckage at the scene , who determined that Rodas was driving 55 mph before the vehicle went out of control . This contradicts the Los Angeles County coroner 's report that car was speeding at more than 100 mph , and the investigations by the Los Angeles County Sherriff 's Office and California Highway Patrol that focused on speed .

Porsche pointed to the discrepancy .

`` As you know , the crash was subject of a very detailed investigation by the authorities , both the California Highway Patrol and the L.A. County Sheriff 's Office , '' said Bernd Harling , Head of Public Relations for Porsche Cars North America . `` The reports showed that driving at a high speed in a negligent manner caused the crash . Both concluded that there was no mechanical defect of the vehicle involved . ''

`` Their investigation disproves in the allegations in the lawsuit , '' he said .
